Is my installaton of CF MX 7 using JVM or not?

Question

I was recently directed to start using some "global logon"
software with my application on our company intranet. I don't know
if it is developed in-house or purchased.
When I talked to the person providing the software, he asked
if I was running "Windows and Coldfusion without JVM" or
"Coldfusion on Windows (using JVM)". I wrote it this way because
that is the way he asked it. Unfortunately, I didn't know the
answer to the question. That's not my expertise. We talked for a
while and he decided I needed his version for "without JVM".
I've been working with the software for a couple of weeks now
and it works, but only partially. It uses a cookie to provide
security information back to the application, then the application
is supposed to decrypt the cookie and get various pieces of info
about the user. I'm only getting a small part of the information.
I'm trying to get more information to determine if he sent me
the wrong version. How would I find out if I'm using JVM or not?
When I look in the CF Admin module at the "Java and JVM" tab, I see
the installation path for JVM is "E:/CFusionMX7/runtime/jre" and
some "JVM arguments" in a lower box. When I look in the "jre"
subdirectory, I find subdirectories for bin, lib, and javaws plus a
bunch of "License" files.
I'm out of ideas to "fix" the software so I'm wondering if
they sent the wrong one. Before you ask, I've already been on the
phone with the provider and the tech support people with no help
(obviously).
The server is running Windows server 2003, IIS, MySQL, and CF
MX 7.
TIA

Yes ColdFusion 5 and earlier where written in C and thus do
not use a
JVM at all and ColdFusion 6 and latter are written Java and
always use a
JVM. But that JVM can be subsumed inside of the ColdFusion
application
and thus only available for use by ColdFusion or it can be
installed
independently of ColdFusion and is thus available for use by
other
Java|JSP applications.
In other words the question is are you using either the
Standard or
Enterprise ColdFusion in Stand-Alone mode which embed the JVM
into the
ColdFusion installation. Or are you using Enterprise in
Multi-Home or
J2EE which install the JVM independently of ColdFusion and
can be used
by other applications.
CF, whether installed in Server configuration or Multiserver
configuration, uses a JVM included with CF. In either of these
configurations, JRun is also used as the J2EE application server
that the CF web app is deployed on. The only difference between
these 2 is this:
* In Server configuration, CF is installed with a
stripped-down JRun designed to run nothing but the CF web app. You
can't deploy other J2EE web apps, nor do you have access to the
full JRun install. In this configuration, the JVM used to run the
stripped-down JRun (and thus the CF web app) is installed at
{CF_Install_Root}/runtime/jre.
* In Multiserver configuration, JRun is installed, then CF
is deployed as a web app on the full JRun install. You can deploy
other J2EE web apps on this JRun install as well as change/access
whatever you'd like within JRun. The JVM included with the full
JRun install and used to run it, and thus the CF web app, is
installed at {JRun_Install_Root}/jre
CF, installed using J2EE configuration, is nothing more than
a web app (.war) that needs to be deployed on your
already-installed J2EE server.
The wording you use makes me think you confuse JVM with J2EE
app server. Especially this sentence:
"But that JVM can be subsumed inside of the ColdFusion
application
and thus only available for use by ColdFusion or it can be
installed
independently of ColdFusion and is thus available for use by
other
Java|JSP applications."
Replacing JVM with J2EE app server makes that sentence more
accurate.
The J2EE configuration doesn't install a JVM at all. It
simply packages up a .war/.ear file for you to deploy on your own
J2EE app server.
